Bostock agreed a temporary move to Griffin Park back in November - scoring twice on his debut against Millwall - but has found life in League One difficult ever since.
Spurs manager Harry Redknapp will now sit down with Bostock as he attempts to reignite the former Crystal Palace star's stuttering career.
Redknapp admits the loan deal has not turned out how he had hoped, and recalled days gone-by when England stars Frank Lampard, Michael Carrick and Rio Ferdinand all cut their teeth successfully in the lower leagues.
"Brentford haven't renewed the loan," Redknapp told the London Evening Standard.
"He was on the bench on Saturday and the Saturday before. But they haven't got a divine right to play because they come from Tottenham. If they're not playing well enough then they don't get picked, do they?
"I keep harping back to when I loaned boys like Rio and Frank out. Frank went to Swansea and was fantastic. Michael Carrick was at Swindon and I was getting calls saying they'd not seen anyone like him since Glenn Hoddle.
"And then you know you've got a player, don't you? That's what you're looking for when you loan them out, you're looking for them to make a real impact wherever they go. And when you get them back you think, 'Stick him in the team'. That's what you want."
And while the robust style of football favoured in League One presents a different challenge altogether for younger players, Redknapp admits it is important to be able to adapt.
"It's a different kind of football but Frank did it when he was at Swansea," he said.
"I went down to see him play at the Vetch, ankle-deep mud, and he was fantastic. It didn't bother him, he got on with it. You have to adjust.
"He's (Bostock) got terrific ability, you just hope he will do it. Maybe I need to get him working and training with the first XI, get him in the squad and see what he can do."
